Abstract
Recent reports on the halogenation of alkenes to vic-dihalogenides by treatment with diaryltellurium () derivatives as well as the reported debromination of vic-dibromides to afford olefins with diaryl telluride () derivatives suggest that these reactions are reversible and the equilibria is shown in eqn.(1). 1–4 On the other hand, organoselenium () derivatives are useful as halogenating agents for olefinic substrates since similar ...
